Some people will not ask someone with an amputated arm how they lost it. I am not one of those people. After the old guy told me he was a retired faller I asked him, "You lose your arm at work?"
"Yes," he told me, "years ago. Only mistake I ever made in the woods. Slipped and sawed my arm clear off. Ed," he continued with a nod of his head towards his fishing partner, "kept me alive until the helicopter got me off the mountain."
I asked Ed, "You knew first aid?"
He shook his head. "Not really, but you learn all kinds of shit if you work in the woods long enough."
